Problems solved by technology

The existing commodity antirust oil is a general-purpose antirust oil, and there are still the following main problems when it is used on the valve: 1) the antirust ability is insufficient, and it is easy to rust in hot and humid weather; 2) the viscosity of the antirust oil is relatively high, and it is easy to adhere Sundries, the total weight of the oil film used on the valve exceeds the standard; 3) It is difficult to dry it with hot air at about 60°C within 3 minutes, and there is an unpleasant smell when blowing with hot air

Embodiment 1

[0012] The technical scheme of the present embodiment: a kind of anti-rust oil used for valves mainly includes sodium petroleum sulfonate, zinc naphthenate, lanolin and aviation kerosene; wherein, the parts by weight of each component are: sodium petroleum sulfonate (Molecular weight: 466): 6 parts, zinc naphthenate: 1 part, lanolin: 4 parts, aviation kerosene: 82 parts; each component is mixed, stirred, heated and dissolved to form the anti-rust oil.

[0013] The anti-rust oil produced by the technical solution described in this embodiment is safe and non-toxic; has no unpleasant smell; the anti-rust performance is better than that of the existing anti-rust oil; the total weight of the oil film sprayed on the valve can meet the use requirements of the valve; The anti-rust oil can be dried within 3 minutes with hot air at about 60°C. Sodium petroleum sulfonate, as the main antirust agent, has artificial perspiration resistance, good oil solubility, and is non-toxic; zinc napht...

Embodiment 2

[0014] Embodiment 2, in order to make effect better, when being used for the air valve of domestic use, present embodiment adopts following technical scheme: the parts by weight of each raw material is aviation kerosene: 93 parts, sodium petroleum sulfonate (molecular weight 466): 4 parts , zinc naphthenate: 2 parts, lanolin: 6 parts, mixed and stirred and heated to dissolve to form the anti-rust oil.

[0015] The anti-rust oil produced by the technical solution described in this embodiment is safe and non-toxic; has no unpleasant smell; the anti-rust performance is better than that of the existing anti-rust oil; the total weight of the oil film sprayed on the valve can meet the use requirements of the valve; The anti-rust oil can be dried within 3 minutes with hot air at about 60°C. Sodium petroleum sulfonate, as the main antirust agent, has artificial perspiration resistance, good oil solubility, and is non-toxic; zinc naphthenate, as an auxiliary antirust agent, has good oi...

Embodiment 3

[0016] Embodiment 3, based on embodiment 2, in order to reach the best antirust effect when the domestic valve is used, the present embodiment adopts the following technical scheme: the parts by weight of each raw material are aviation kerosene: 90.5 parts, sodium petroleum sulfonate (molecular weight 466 ): 3 parts, zinc naphthenate: 1.5 parts, lanolin: 5 parts, mixed and stirred and heated to dissolve to form the antirust oil.

[0017] The anti-rust oil produced by the technical solution described in this embodiment is safe and non-toxic; has no unpleasant smell; the anti-rust performance is better than that of the existing anti-rust oil; the total weight of the oil film sprayed on the valve can meet the use requirements of the valve; The anti-rust oil can be dried within 3 minutes with hot air at about 60°C. Sodium petroleum sulfonate, as the main antirust agent, has artificial perspiration resistance, good oil solubility, and is non-toxic; zinc naphthenate, as an auxiliary...

Abstract

The invention discloses rust preventive oil suitable for a valve. The oil is prepared by mixing, stirring, heating and dissolving sodium petroleum sulfonate, zinc naphthenate, lanolin, sodium petroleum sulfonate, zinc naphthenate and aviation kerosene, wherein the sodium petroleum sulfonate serves as a main rust preventing agent; the zinc naphthenate serves as an auxiliary rust preventing agent; the lanolin serves as a main film forming matter; the sodium petroleum sulfonate and the zinc naphthenate serve as auxiliary film forming matters; the aviation kerosene serves as the basic oil of the rust preventive oil; and the rust preventive oil comprises 2 to 6 weight parts of sodium petroleum sulfonate (with a molecular weight of 466), 1 to 4 weight parts of zinc naphthenate, 4 to 8 weight parts of lanolin and 82 to 93 weight parts of aviation kerosene. The rust preventive oil overcomes the defects of poor rust preventive capability, relatively higher viscosity, easy adhesion to other foreign matters, over gross weight of oil films used on the valve, difficulty in drying by hot air of 60 DEG C within 3 minutes, bad odor and the like of the conventional rust preventive oil for the valve.

Description

technical field [0001] The invention relates to a chemical oil liquid, in particular to an antirust oil used for valves. technical background [0002] The valve is a key part of the engine. After the valve is completed, it is not allowed to rust and must be treated with anti-rust. The requirements for the anti-rust oil of the valve are: 1) The anti-rust period is more than one year; 2) The anti-rust oil film on each valve The total weight (including oil film and oil film debris) shall not exceed 0.5mg; after dissolving the oil film with gasoline, the maximum size of a single particle in the insoluble matter is less than 0.2mm; 3) anti-rust oil is safe, non-toxic, and has no unpleasant smell; 4) The anti-rust oil has moderate volatility: below 30°C, the volatility should not be too strong, so as to ensure that the viscosity does not change too much during the production process; at the same time, it should be able to be dried within 3 minutes with hot air at about 60°C. The ...
